Strengths:Ease of use, great value if you already have an ipod nano, excellent wesite to download run data onto

Weaknesses:Accuracy is questionable, needs callibrating to get to around 97% and this varies if you run at differnet speeds.

Overall:Excellent value if you already have an Ipod nano, Very easy to use and very good website that stores your data. matbe more for beginners as accuracy is questionable but overall I'm really glad I bought one.

Weaknesses:Not quite as cushioned as my asics Kayano 13's but maybe they will last longer.

[Update 29/07/08] The sole started to come apart afer about 350 miles which is a bit diisappointing, still wearable although I won't run long in them anymore. Still OK after almost 500 miles though

Overall:Very capable and stable shoes, no need to break in, Nike + capabilty, Good for all distances although not the most cushioned for heavier runners. Geeat Vaule - I got these for £50 from www.dorunning.co.uk.
